Bellicum Pharmaceuticals, Inc. (Nasdaq:BLCM) and Ospedale Pediatrico Bambino Gesù (OPBG), a leading European pediatric research center and hospital, today announced that they have entered into an expanded collaboration focused on preclinical and clinical development of CD19 and other CAR T and TCR therapeutics engineered with Bellicum's CaspaCIDe ® molecular safety switch technology.

The two organizations agreed to jointly develop CARs and other cell therapies discovered by OPBG and engineered with Bellicum's CaspaCIDe safety switch, which is designed to reduce or eliminate cells that become toxic or are no longer needed. Under terms of this agreement, Bellicum agreed to provide financial support to the research collaboration in exchange for exclusive worldwide rights to commercialize certain cell therapies that are developed, while OPBG maintains rights for research purposes. OPBG will conduct research and clinical studies of CAR T and TCR therapeutics in pediatric patients, with initial CD19 CAR T and GD2 CAR T clinical trials in pediatric acute lymphoblastic leukemia and neuroblastoma patients, respectively, expected to start in 2017. In addition, OPBG agreed to manufacture European clinical trial supplies for the investigational programs, as well as Bellicum's PRAME-targeted TCR, BPX-701, in its GMP facility.

"The Ospedale Pediatrico Bambino Gesù is among the world's leading cell and gene therapy research centers and hospitals, and we are enthusiastic about working with them to develop controllable engineered T-cell therapies," commented Tom Farrell, President and CEO of Bellicum Pharmaceuticals. "This agreement builds on our highly successful clinical development collaboration with OPBG on BPX-501, our CaspaCIDe-enabled T-cell therapy in clinical development for patients undergoing haploidentical hematopoietic stem cell transplant. OPBG has developed several exciting and innovative new cell therapies, including a CD19 CAR T cell that we believe will be highly differentiated by virtue of our clinically validated CaspaCIDe safety switch."

"We have a highly productive and synergistic relationship with Bellicum, and look forward to building on our present research collaboration," commented Dr. Mariella Enoc, President of the Board of Directors of OPBG. "The combination of Bellicum's innovative safety switch technology and our cell and gene therapy expertise, clinical study network and GMP vector and cell manufacturing capabilities, makes this an ideal partnership to rapidly advance controllable cell therapies that could benefit children and adults with life-threatening cancers throughout the world."
